We look at the division of 39872944 by 633 
The aim is to understand the frequency of 633 in 39872944.

Step 1:
3 divided by 633 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 633

On to step 2:
633 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 633

On to step 3:
If we divide 398 by 633, we get 0 and a remainder of 398.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 398, we get 398.
Append the next digit (7) from the dividend to 398 and continue with: 3987 / 633

Going ahead to step 4:
633 can be fit into 3987 6 times, resulting in a remainder of 189.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 3798 from 3987 leaves us with 189.
Append the next digit (2) from the dividend to 189 and continue with: 1892 / 633

Going ahead to step 5:
When dividing 1892 by 633, we get 2 with a remainder of 626.
Put 2 as the next digit of the answer. 
Result so far: 62.0
The remainder is 626 after subtracting 1266 from 1892.
Take the next digit (9) from the dividend and append it to 626, then repeat: 6269 / 633

Going ahead to step 6:
If we divide 6269 by 633, we get 9 and a remainder of 572.
The next digit of our result is 9. 
Result so far: 629.0
Subtract 5697 from 6269 to get 572.
Grab the next digit (4) from the dividend, add it to 572, then carry on: 5724 / 633

Going ahead to step 7:
633 goes into 5724 9 times with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 6299.0
The remainder is 27 after subtracting 5697 from 5724.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 633

On to step 8:
The number 633 fits into 274 0 times, leaving a remainder of 274.
Write down 0 as next digit of the result. 
Result so far: 62990.0
Deduct 0 from 274 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 9:
If we divide 2740 by 633, we get 4 and a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 62990.4
The remainder is 208 after subtracting 2532 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 10:
If we divide 2080 by 633, we get 3 and a remainder of 181.
The next digit of our result is 3. 
Result so far: 62990.43
The remainder is 181 after subtracting 1899 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 11:
633 can be fit into 1810 2 times, resulting in a remainder of 544.
Use 2 as the next digit of our solution. 
Result so far: 62990.432
Subtract 1266 from 1810 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 12:
The number 633 fits into 5440 8 times, leaving a remainder of 376.
The next digit of our result is 8. 
Result so far: 62990.4328
Deduct 5064 from 5440 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 13:
633 goes into 3760 5 times with a remainder of 595.
Write down 5 as next digit of the result. 
Result so far: 62990.43285
If we take 3165 away from 3760, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 14:
When dividing 5950 by 633, we get 9 with a remainder of 253.
Write down 9 as next digit of the result. 
Result so far: 62990.432859
Deduct 5697 from 5950 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 15:
The number 633 fits into 2530 3 times, leaving a remainder of 631.
Put 3 as the next digit of the answer. 
Result so far: 62990.4328593
If we take 1899 away from 2530, we end up with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

On to step 16:
When dividing 6310 by 633, we get 9 with a remainder of 613.
The number 9 becomes the next digit in our result. 
Result so far: 62990.43285939
Subtracting 5697 from 6310 leaves us with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

After the division, we end up with 62990.43285939 and a remainder of 6.13e-07.
